Medium View solution > View more More From Chapter Laws of Motion View chapter > Revise with Concepts WebThe coefficient of restitution ( COR, also denoted by e ), is the ratio of the final to initial relative speed between two objects after they collide. It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision. A perfectly inelastic collision has a coefficient of 0, but a 0 value does not have to be perfectly inelastic. ols fitted values
